The Seal of the Grimoire
Mei Misaki has always been a good student, so she is completely shocked when she is suddenly summoned by the student council. Even more, they seem to think of Mei as a troublemaker. Led by the handsome Rem Kaginuki, the student council-also consisting of Urie Sogami, Shiki Natsumizaka and Mage Nanashiro-tries to question her, but it soon becomes clear that they have ulterior motives.
However, this is only the beginning. When a group of mysterious men break into her house, her life is turned upside down, and Mei gets drawn into a world of vampires and devils. Both groups are searching for the "Grimoire," a forbidden item allowing its owner to rule the world. The return of her best friend Lindo from overseas gives her hope, but even he appears to be hiding something. In a world filled with secrets, Mei questions whom she can trust in this dark corrupted fairytale, while the handsome and dangerous members of the student council compete for her attention.
